The Prophet ﷺ used to love to start doing things from the right side whenever possible, in performing ablution, putting on his shoes, and combing his hair. (Al-Ash'ath said: The Prophet ﷺ used to do so in all his affairs.)  

كَانَ النَّبِيُّ ﷺ يُحِبُّ التَّيَمُّنَ مَا اسْتَطَاعَ فِي طُهُورِهِ وَتَنَعُّلِهِ وَتَرَجُّلِهِ وَكَانَ قَالَ بِوَاسِطٍ قَبْلَ هَذَا فِي شَأْنِهِ كُلِّهِ
